The MSSQL schema is now brought in-line with the MySQL schema.
Additionally, various issues that prevented successful installation or
updates via MSSQL were fixed, notably with respect to creating bits of
the database should other bits already exist as well as issues with
previous updater patches not working correctly.
Additional MSSQL bugfixes will come in separate patches, as they are less
related to the schema/install/upgrade process.
